Abstract: The present invention relates to a plug-ﬂow aerator with a semi-open water bearing. A semi-open water bearing sleeves the lower part of a hollow transmission shaft by a 5 water bearing sleeve core. The semi-open water bearing includes a left body and a right body which form a semi-open symmetrical structure. The left body includes a left planar ﬂange, longitudinal ﬂanges at two sides, a middle tubular body, a bearing working surface coating, and anti-drop barb bodies, wherein one end surface of the middle tubular body is connected with the left planar ﬂange, and the longitudinal 10 ﬂanges at two sides are connected to edges of upper and lower openings of a semicircular tubular structure, the plurality of anti-drop barb bodies which are distributed as a whole in rows and columns along the circumferential direction and column of an internal-diameter hole of the middle tubular body are welded and connected to the surface of the internal-diameter hole, the bearing working surface 15 coating uniformly covers the surface of an inner hole of the middle tubular body so as to be used as a bearing working surface, and the anti-drop barb bodies are naturally submerged and embedded in the bearing working surface coating. By adopting the composite structural mode of the semi-open water bearing, the plug-ﬂow aerator is stable and reliable in transmission support and convenient and rapid to install and 20 maintain.

Patent NL-7600877-A (NL)
IPC: B60K13/02
Filed: 1976-01-28
Abstract: A telecommunication switching arrangement is described wherein each seizable switching component, i.e., a component in an idle condition, is so marked by application of an idle potential to a test point by means of a seizing circuit in that switching component. The busy condition is indicated by the absence of the aforementioned potential. The condition of the switching component is sensed by a test switching device having an internal impedance corresponding to that of a preceding switching component. The latter device accomplishes its task by completing a test and seizure circuit including the aforementioned test point. If a switching component being tested is already seized by another switching component, it will have been blocked by a blocking circuit in the other switching component. Such blocking is brought about by applying a potential differing from the idle potential from the blocking circuit via an auxiliary test switching means in the other switching component, which has an internal impedance identical to the test switching means. For seizure, the seizing circuit in each switching component is fed from a constant current generator proportioned in accordance with the number of switching components testing that switching component. The foregoing proportion is the inverse of the number of switching components testing in parallel.

Title: Catalyst regeneration with reduced nitrogen oxide emission - using three regeneration zones for coke and carbon mon:oxide combustion
IPC: B01J29/90
Filed: 1982-02-11
Abstract: Regeneration of a particulate catalyst contaminated with N-contg. coke is affected by dividing the catalyst into 2 portions (1 and 2) and carrying out the following steps: (a) introducing portion 1 into a 1st regeneration zone, where it is contacted with sufficient O2-contg. regeneration gas to burn off all the coke, to burn all the CO formed in the 1st zone, and to provide a 1st off-gas contg. nitrogen oxides (NOx) and at least 1 vol.% residual O2; (b) contacting portion 2 with the 1st off-gas in a 2nd regeneration zone, where the residual O2 burns coke off the catalyst and burns CO to produce an O2-free 2nd off-gas, and NOx are coverted to N2; (c) passing the 2nd off-gas to a 3rd regeneration zone, where all the CO formed in the 2nd zone is burned with additional O2 in contact with coke-free catalyst. The process is esp. applicable to fluid catalytic cracking catalysts. It allows high levels of coke removal to be achieved while producing a regenerator flue gas with low CO and Nox concns.

Patent NL-8502330-A (NL)
IPC: C02F3/28
Filed: 1985-08-23
Abstract: For the anaerobic purification of waste water it is difficult to maintain good operative contact between sludge particles with bac­teria and water to be purified, i.e. sufficiently freely floating sludge particles, which means avoiding the formation of a dense settled layer of active sludge and avoiding easy washing away of sludge with the water in the usual upward flow thereof. The inven­tion proposes the generation of a downward flow of the water to be purified in a reaction chamber (2) and the introduction of an oxygen-free gas to contact the active sludge particles so that gas bubbles adhere thereto and keep them floating as much as possible notwithstanding said downward flow. Any sludge moving downwards with the water too much enters a flotation device (6) near the top of the reaction chamber (2), from which it overflows (7) to be returned wholly or partially to the reaction chamber. Preferably, the reaction chamber has a central riser pipe (3) leading water with some sludge from the bottom of the reaction chamber (2) upwardly to the flotation device (6).

One side of the hollow-body part is formed with a facet 5 which will subsequently be operative for the engagement of a welding electrode for press welding. The neck part (21) is formed with an internal screwthread 6, and that side of the spherical hollow-body part which is opposite the facet 5 is drilled to provide an opening 7 for connection of the radiator. <IMAGE>
